Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center).
For example, this binary tree is symmetric:
1
/ 2 2
/ \ / 3 4 4 3
But the f...

Given a binary tree, find its maximum depth.
The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node.
此题和求二叉树的最短路径几乎一模一样。

Given a binary tree and a sum, determine if the tree has a root-to-leaf path such that
adding up all the values along the path equals the given sum.
For example:
Given the below bin...
